P4596

DESCRIPTION

The UTC P4596 consists of 3A step-down switching regulator

with PWM control which includes a reference voltage source,

oscillation circuit, error amplifier, internal PMOS and etc.

The UTC P4596 can provide low-ripple power, high efficiency,

and excellent transient characteristics and an enable function, an

over current protect function and a short circuit protect function

are built inside, And the PWM control circuit can vary the duty

ratio linearly from 100 down to 0%. This converter also includes

an error amplifier circuit as well as a soft-start circuit that prevents

overshoot at startup. These ICs can work as step-down switching

regulators with the addition of an internal P-channel Power MOS,

a coil and a diode connected externally. They provide such

outstanding features: low current consumption. It is also suitable

for the operation via an AC adapter because this converter can

accommodate an input voltage up to 40V.

FEATURES

* Input voltage：8V~40V

* Duty ratio：0%~100% PWM control

* Enable with Soft-Start function

* Oscillation frequency can be set by outside resistance

* Current Limit, SCP and OTP
